Display Content for a Specific Role - Drupal

Sometimes, is can be a requirement to only allowed a specific group of users to view some content on a page. I'm not talking about showing or hiding the entire page to a specific role.
What I am talking about is that an authenticated user sees some different or additional content than an anonymous user will see on the same page.
I recently had a requirement to do just this on a community website that I am building. I needed to show a discount Coupon Code to registered users but not to anonymous users.
This is easily achieved by changing the content type to PHP and inserting the following snippet of code.
<?php
global $user;
$approved_roles = array('authenticated user', 'super user');
if (is_array($user->roles)) {
if (count(array_intersect($user->roles, $approved_roles)) > 0) {
print '<p>Use Coupon Code: <strong>My Code</strong></p>When <a href="http://www.example.com">Ordering Products</a>';
}
else {
print '<p><a href="/user/login?destination=current-page-url">Login</a> | <a href="/user/register">Register</a><br /> To get Coupon Code.</p>';
}}
?>Just a few things to note about the about PHP snippet.
- This allows users in the "super user" and "authenticated user" groups to see the coupon code.
- Anonymous users are prompted to Register or login to see the Coupon Code.
- The "current-page-url" should be replaced with the url of the current page. This will allow a registered user to redirect straight back to the same page after logging in.
